Hi these plugs i have are Bosch HR 78 they were sold to me for my Mercedes 260e .But after fitting them ,i found out that they are not any good in my M103 engine . So i was told on the forum .. I had no problem with them . They should have none resistor plugs fitted .After checking the bosch site for the type of car they do fit ,and all i can find are Mercedes . types .As anyone on the forum used them ,or are still useing them .And if so in what model of Mercedes are they in. Or are they not suitable for Mercedes
